Battery Mini-Breaker Datasheet © 2021 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 09/08/21 MHP-TAM Series Breakers (Thermal Cutoff Devices) MHP with Thermal Activation RoHS and Halogen-Free Compliance RoHS Compliant Halogen Free per IEC 61249-2-21 Application Environment The device is intended to be used for applications which are common for general electronic devices. Usage in any of the special environments or conditions as listed below may adversely impact the device performance and therefore users should carefully consider conditions of use of the end product and the potential impact on reliability or performance when incorporating this device into any design to carefully examine the actual performance and reliability of the device.

  • Environment where the devices are exposed to water, oil, chemical solutions, and/or organic solvents.
  • Installation in an area close to a heat source or adjacent to or near flammable objects such as plastic wires.
  • Environment in which the device is constrained by pressure, sealing or resin coating.
  • Environment where water condenses on the device.
  • Environment with salt air or with corrosive gas such as CL2, H2S, NH3, SO2, and NOX.
  • Environment with grit and dust and/or under direct sunlight.
  • Environment outside of recommended operating temperature. Precautions for Rating a. The power supply voltage must be less than or equal to the rated voltage of the device. Operation above the voltage rating may result in device damage, smoke or flame. b. Designs must be selected in such a manner that the device hold current is higher than the normal current value in the circuit. Selecting device hold current that is too low for the application may interrupt the circuit under normal usage conditions. c. This product should not be used in an application where the maximum short circuit current available exceeds the rated maximum breaking current of the product. d. The devices are intended for protection against damage caused by occasional over current or over temperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated. e. The devices may not perform as specified if mechanical pressure is added while the device is in the tripped state or exposed to temperature conditions over 100°C or in temperature conditions under -30°C.

Revised: 09/08/21 MHP-TAM Series Breakers (Thermal Cutoff Devices) MHP with Thermal Activation Precautions for Handling The device is composed of plastic parts, please do not clamp or dent the housing with a tool as this might cause a resistance increase and product damage. When welding product terminals or mounting the breaker on a battery (cell), please be careful not to apply excessive bending, twisting or force on the product and terminals. The excessive stress might cause a resistance increase or product damage. Please refer to following cautions: 1. Do not apply more than 10N bend force to product. (Fig. M3) 2. Do not apply more than 1 .5cN/m twist torque to the product. (Fig. M4) 3. Do not apply more than 20N deflection force to product. (Fig. M5) 4. Do not apply more than 2N force to the terminals. (Fig. M6) 5. Do not apply more than 0.6cN/m twisting torque to the terminals. (Fig. M7) 6. Do not bend the terminal base more than 45° when the product is mounted in a fixed position. (Fig. M8) 45° 45° 45° 45° 45° 45° 45° 45° 45° 45° 45° 45° Figure M3 Figure M6 Figure M4 Figure M7 Figure M5 Figure M8 Product terminals can be welded using direct welding and series welding methods. In either case, please use a suitable jig so that the device will not be subjected to the stress conditions listed above. Pull strength and detach strength of the terminal welds are per user requirements. However, if the welding is controlled by resistance, the measurement should be made as close as possible to the weld point by a “4-point clip method” using milliohm meter to ensure accuracy. Avoid putting stress on the device, as listed above, when a jig, fitting or additional welding process is used. Please reconfirm the resistance value whenever a new process is added.
